I'm still new to lasers but I've been doing a lot of research the last couple weeks. I first thought that I wanted to buy a big bad high power laser that I could play with but then I realized that something like that requires safety precautions and equipment -- not something I can just carry around with me to play with or show others. So that brings me to my question. Does anybody carry a laser with them as part of their everyday carry? What type and power is safe to just have with me and use without requiring safety glasses for everybody nearby.
